Definitions

  • the present invention relates to a turbo compressor.
  • turbo compressors used, for instance, when compressed air is produced and supplied to demanding places such as a plant, two-stage turbo compressors and three-stage turbo compressors have been known in response to required pressure of the compressed air.
  • These types of turbo compressors have a plurality of compressor blades rotated by a pinion shaft connected to a large gear shaft via an acceleration device.
  • operations of causing a fluid compressed by first stage compressor blades to be cooled by a cooler, then guiding the cooled fluid to second stage compressor blades to compress the cooled fluid again, and guiding the compressed fluid to a separate cooler to cool the compressed fluid are sequentially performed.
  • the two-stage turbo compressor As the two-stage turbo compressor, a configuration in which the oil tank is integrally assembled to a side portion of a box body housing the cooler is known (see Patent Document 1). However, it is difficult to manufacture the configuration adapted to integrally assemble the box body and the oil tank like the turbo compressor disclosed in Patent Document 1. Accordingly, the two-stage turbo compressor is unfavorable in terms of the productivity and production costs thereof.
  • Patent Document 1 Japanese Patent No. 3470410
  • Patent Document 2 Japanese Unexamined Patent Application, First Publication No. 2004-308477
  • the present invention has been made keeping in mind the above problems and is intended to provide a turbo compressor that has a simplified configuration and is more compact, compared to a conventional turbo compressor.
  • a turbo compressor which has first, second, and third stage compressor blades rotated by two pinion shafts connected to a large gear shaft via an acceleration device, and which comprises a cast integral casing which forms an acceleration unit cover housing the acceleration device, compression unit covers housing the compressor blades, and first, second, and third stage cooler chambers which are disposed at a lower portion thereof so as to individually house first, second, and third stage coolers in a state in which the first, second, and third stage coolers are arranged in parallel in an elongated shape and which are spatially connected to the compression unit covers by fluid passages.
  • An oil tank is integrally formed with the cast integral casing so as to run along a longitudinal innermost side of the first, second, and third stage cooler chambers arranged in parallel.
  • the cast integral casing may have a main oil pump and an oil cooler disposed thereon so as to pump up and cool the oil in the oil tank and then to feed the cooled oil to the large gear shaft, the acceleration device, and the pinion shafts.
  • the cooler chamber located at a parallel-arrangement-directional end of the cooler chambers extends to avoid the oil tank, and an extension part thereof may have a fluid outlet and a drain outlet.
  • the oil tank is integrally formed with the cast integral casing so as to run along a longitudinal innermost side of the first, second, and third stage cooler chambers. Accordingly, it is possible to obtain the turbo compressor having a compact configuration. Further, a volume of the oil tank of the turbo compressor can be sufficiently secured.
  • the turbo compressor can have a more compact configuration.
  • a drain can move along with a flow of fluid to successfully discharge from the drain outlet.

  • FIG. 5 is a cross-sectional view taken in a direction V-V of FIG.
  • FIG. 6 is a cross-sectional view taken in a direction VI-VI of FIG. 1 .
  • FIGS. 1 to 6 show an example of a turbo compressor according to an embodiment of the present invention.
  • FIG. 1 is a front view of the turbo compressor
  • FIG. 2 is a plan view of FIG. 1

  • reference numeral 1 indicates a cast integral casing constituting a main body of the turbo compressor
  • reference numeral 2 indicates a motor constituting a driving device of the main body of the compressor.
  • the motor 2 is installed on a motor bed 3 assembled to the cast integral casing 1 .
  • the motor 2 is connected to a large gear 30 of an acceleration device 5 the cast integral casing 1 via a coupling 4 a and a large gear shaft 4 .
  • Two pinion shafts 6 and 7 are meshed with and provided on an outer circumference of the large gear 30 of the acceleration device 5 .
  • first stage compressor blades 8 and second stage compressor blades 9 are attached to one pinion shaft 6
  • third stage compressor blades 10 are attached to the other pinion shaft 7 .
  • a first stage cooler chamber 11 a , a second stage cooler chamber 12 a , and a third stage cooler chamber 13 a are provided on a lower inner side of the cast integral casing 1 .
  • the first stage cooler chamber 11 a , the second stage cooler chamber 12 a , and the third stage cooler chamber 13 a are integrally formed in a state in which the first stage cooler chamber 11 a , the second stage cooler chamber 12 a , and the third stage cooler chamber 13 a are arranged in parallel in a front-back direction.
  • a first stage cooler 11 (inter cooler), a second stage cooler 12 (inter cooler), and a third stage cooler 13 (after cooler) are respectively inserted in the cooler chambers 11 a , 12 a , and 13 a .
  • the first stage cooler 11 , the second stage cooler 12 , and the third stage cooler 13 are inserted from the left side of FIGS. 1 and 2 to innermost portions of the cooler chambers 11 a , 12 a , and 13 a via the openings.
  • the cooler chambers 11 a , 12 a , and 13 a are connected to compression unit covers 8 a , 9 a , and 10 a formed so as to cover the compressor blades 8 , 9 , and 10 via fluid passages, respectively.
  • the fluid which is introduced from a filter F and is compressed by the first stage compressor blades 8 , is guided to the vicinity of an insertion side of the first stage cooler chamber 11 a by the fluid passage 14 , and is cooled by the first stage cooler 11 . Then, the cooled fluid is guided to the second stage compressor blades 9 having the same axis as the first stage compressor blades 8 by a fluid passage 15 provided at an innermost portion end and is compressed by the second stage compressor blades 9 .
  • the fluid compressed here is guided to an innermost end of the second stage cooler chamber 12 a by a fluid passage 16 and is cooled by the second stage cooler 12 .
  • the cooled fluid is guided to the third stage compressor blades by a fluid passage 17 provided nearby and is compressed by the third stage compressor blades 10 .
  • the fluid compressed here is guided to the vicinity of the third stage cooler chamber 13 a by a fluid passage 18 , is cooled by the third stage cooler 13 , and then is extracted upwards from a fluid outlet 19 installed on an innermost end of the third stage cooler chamber 13 a .

  • an oil tank 21 is integrally formed at an insertion-directional innermost side of the cooler chambers 11 a , 12 a , and 13 a arranged in parallel in a horizontal direction so as to run in a direction in which the cooler chambers 11 a , 12 a , and 13 a are arranged in parallel.
  • an extension part 22 is formed at an insertion-directional innermost side of the coolers.
  • the drain outlet 20 is formed below a fluid outlet of the fluid passage 15 that is open to an upper side of the extension part 22 . Accordingly, since the oil tank 21 is installed alongside the innermost side of the cooler chambers 11 a , 12 a , and 13 a arranged in parallel, despite being formed away from the extension part 22 , the oil tank can have a sufficient volume.
  • An upper portion of the cast integral casing 1 shown in FIGS. 1 and 3 is provided with a main oil pump 26 pumping up the oil of the oil tank 21 via a suction pipe 25 , and an oil cooler 27 introducing and cooling the oil of an outlet of the main oil pump 26 from one end thereof.
  • a lubricating system is configured to force the oil, which is cooled by the oil cooler 27 and is guided out of the other end, to pass through an oil filter 28 , and then to be fed to and lubricate lubrication parts such as the large gear shaft 4 , the acceleration device 5 , and the pinion shafts 6 and 7 by a feed pipe 29 .
  • the oil used for the lubrication flows down to return to the oil tank 21 .
